Chatterbox does not book appointments itself. It answers scheduling questions using whatever your website has already published — hours, service days, typical lead times — and when a visitor needs an actual slot, it asks for their contact details instead of guessing one for you.

A visitor on a salon, clinic or contractor's site types "can I get a slot on Thursday?" into the chat widget before they type anything else. It is a fair question to ask a chat window, and a fair one to ask before you install one: does the thing actually take the booking, or just talk about it?
Does Chatterbox reserve the slot?
No. There is no calendar behind the widget and no booking engine it writes to. What it does is answer from material your business has already published or supplied — pages, FAQs, documents — the same way it answers a question about price or delivery area. A scheduling question gets the same treatment as any other: if your site says something about it, the visitor gets that; if not, Chatterbox says it cannot find the answer rather than inventing a time that sounds plausible.
What it can tell a visitor about your availability
If your hours, service days or typical turnaround are written down somewhere the crawl reaches — a hours page, an FAQ, a service description — the widget can repeat that back correctly. "We're open Tuesday through Saturday" or "jobs booked this week usually start within three days" are exactly the kind of published fact Chatterbox is built to surface, because they came from your own site rather than from a guess. The bot is only ever as current as that page is, so a hard-coded page from two seasons ago will answer with two-seasons-ago hours.
What happens when the question needs a real slot
A visitor asking for "Thursday at 2pm specifically" is asking something no page on your site answers, because a specific slot depends on what is already booked, not on a general statement of hours. That's the same gap Chatterbox hits with a custom quote or an unusual job: its source material doesn't cover it, so instead of picking a time that seems reasonable, it asks the visitor for their name and contact details so a person can confirm the real one. The visitor leaves their details while they're still on the page, rather than closing the tab to call during business hours.
Why not have it pick a time anyway
A guessed slot is a commitment stated in your business's voice on your own website. If the visitor shows up and the time was never actually open, the awkward conversation is yours to have, not the widget's. Chatterbox's answer to that risk is the same one it gives everywhere else its material runs out: say it doesn't know, and collect enough to follow up properly, rather than produce a confident answer nobody can stand behind.
Deciding what to publish before you turn it on
If booking questions are common for your business, the useful preparation isn't building a scheduling feature into the widget — there isn't one — it's making sure your hours, service days and lead times are actually written down somewhere the crawl can find them, so the widget answers those parts on its own and only hands off the part that genuinely needs a person: confirming the specific slot.
